CAR-WALL STRUCTURE.

App1ication filed May 26, 1919.

To all whom it 'may concern.'

Be it known that I, GEORGE IV. Sninni., a citizen of the United States,residing at Bloomington, in the county of McLean and State of Illinois,have invented certain new and useful Improvements in Car-TallStructures, of which the following is a specilication.

My invention relates to a wall construction for railway cars,particularly freight cars, suitable for the sides of the car but moreespecially for the ends thereof, which latter, because of the tendencyof the cargo to shift and of the superstructure of the car to weave, areparticularly subject to strains which, if not prevented, shorten thelife of the car materially.

My invention has for its object to provide a metal railway car wallstructure which will be very light, strong and rigid and may bemanufactured and assembled at relatively low cost. The structure, whenapplied to form the end wall of the car, may be used either on old carsfor repair purposes or in the construction of new cars.

The invention is illustrated, in certain preferred embodiments, in theaccompanying drawings wherein Fig. l is an end elevation of thesuperstructure of a railway box car, the end wall of which isconstructed in accordance with the invention.

Fig. 2 is a plan view on line 2--2 of Fig. 1.

Fig. 3 is a vertical sectional view on line 33 of Fig. 1.

Fig. 4 is an enlarged vertical sectional View illustrating the formationof one of the reinforcing ribs.

Fig. 5 is a vertical sectional View showing a modified construction, and

Fig. 6 is a similar view illustrating another modification.

Like characters of reference designate like parts in the several figuresof the drawings.

The invention is illustrated and will be described as embodied in an endwall structure for a railway boX car, the superstructure of which isotherwise made of wood and of conventional type. 10 designates the endsill of the car, 11 the side sills, 12 the Hoor, 13 the corner posts, 14the. side sheathing, 15 the side plates, 16 the ridge pole, 17 the roofboards, and 18 the linings of the side walls.

The end structure consists, in the embodiment shown, of four plates 19,20, 21 and 22,

overlapped and secured together by rivets 23. The plates are formed ontheir vertical edges with flanges 24 which are secured by bolts 25 tothe corner posts 137 the flanges overlapping the side sheathing boards14. The upper sheet 19 is preferably formed with an inturned flange 26which takes the place of the end plate and supports the ridge pole 16.Sheets 19, 20 and 21 are formed at their lower edges with channel-likeribs27 which are produced by rolling the plates while hot. The channelsare substantially rectangular in cross section but the rolls are soformed that lillets or thickened portions 28, 29, 30, 31 are formed atthe corners of the channels. This thickening of the metal at the cornersof the ribs gives the ribs additional strength and rigidity. The ribbedportion of each sheet 19, 20, 21 overlaps the upper edge of the adjacentplate, the plates being riveted together on opposite sides of each rib.The lower plate 22 is flat and is secured to the end sill 10 by bolts32.

In Fig. 5 I have shown a similar construction except that the plates 33are formed with angular reinforcements 34 at their edges. In the rollingoperation the corners are illeted as before to increase the strength ofthe rib.

In Fig. 6 thev lower edge of the plates 35 are rolled to form bulbangles 36.

I claim:

1. A metal car wall structure formed with integral reinforcing ribs eachcomprising a web at an angle to the body of the wall having an angularlydisposed iiange, portions of which ribs are thicker than the body of theplate.

2. A metal car wall structure formed with integral channel-likereinforcing ribs, poi'- tions of which are thicker than the body of theplate.

3. A metal car wall structure formed with integral reinforcingchannel-like ribs generally rectangular in cross section but withfillets at the angles giving increased thickness at these places.

4. A metal car wall structure comprising a rolled plate formed with areinforcing rib angular in cross section and projecting from the plate,a portionof which rib is thicker than the body of the plate.

5. A metal car wall structure comprising a rolled plate formed with achannel-like reinforcing rib a portion of which is thicker than the bodyof the plate.

and joined together and provided at their junctions with integralchannel-like ribs, portions of which are thicker than the other parts ofthe plate.

9. A metal car Wall structure consisting of a plurality of rolled platesoverlapped and joined together and provided at their junctions withchannel-like ribs having fillets at their angles giving increasedthickness at these places.

l0. A metal car Wall comprising a plurality of plates the body portionsof Which are overlapped and joined together at their edges, one of eachpair of overlapping edges having an angular formation integral with theplate, the angle "portion of which is thicker than the body of theplate.

l1. A metal car Wall structureconsisting of a plurality of plates, Whichare overlapped at their margins, one plate of each pair of overlappedplates being formed With a rib comprising an outstanding web, the outerportion of Which is 'thicker than the body of the plate.
